I have been doing SEO for two years and didn't have any experience in email marketing. Recently, my boss asked me to get a large number of email list in about two weeks. I know the best way to do email markeing is to build the list yourself, but the time is urgent. It seems impossible to build such a large list within a short time. So here are my thought: 1. Buy email list Pros: the most quick way Cons: authenticity of the list, there are many scammers out there. 2. Scrape the email list using software Pros: Cheap and relative Cons: time-consumering 3. PPC with specific landing pages Pros: High quality Cons: needs much more money P.S the niche is targeted for high shcool students. Any suggestion would be highly appreciated.
